Patented Mar. 9, 1954 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to improvements in pumps, and particularly to ashallow well pump of the cyclone type, in which water is lifted throughcentrifugal action within an inverted cone or tapered sleeve, andprovides a highly efiicient pump for shallow wells and for water liftfrom irrigation ditches, canals, creeks, rivers, ponds, and lakes fordiversion to fields at elevations above the level of the water supply,providing volume of delivery in conformity with the speed of rotation ofthe sleeve and the angularity of the walls of the sleeve, the pressurecoincidently increasing with increased angularity.

This pump is intended to deliver large volume at low pressure with aminimum of power, and is therefore particularly suited for irrigationpurposes, the water delivery efficiency being higher than that deliveredby centrifugal and reciprocating pumps, since the water resistance andfriction present in the latter types of pumps is practically absent inmy new pump.

The objects and advantages of the invention are as follows:

First, to provide a water lift pump which is particularly suited toshallow well and irrigation pumping.

Second, to provide a pump as outlined which is relatively simple inconstruction and light in weight.

Third, to provide a pump as outlined in which the pumping elementconsists of a frustum of a cone with the base forming the top anddischarge end.

Fourth, to provide a pump as outlined in which the sleeve is providedwith spiral ribs to decrease frictional resistance between the walls ofthe cone and the water being lifted.

Fifth, to provide a pump as outlined with terminal cupping vanes forinitiating lift from shallow water supply sources such as irrigationditches.

Sixth, to provide a pump as outlined in which the pump is rotatablysuspended from a suitable support, and free of supports and bearings atthe lower end.

Seventh, to provide a pump as outlined which is simple in construction,easy to install, capable of installation on a vehicle for transportationand use as needed at different locations on a farm, ranch or the like,and economical to manufacture.

In describing the invention reference will be had to the accompanyingdrawings, in which:

Fig. 1 is a vertical elevation through the invention shown partly insection.

Fig. 2 is a top plan view of the invention with parts of the dischargechamber broken away and the suspension spider and head being removed.

Fig. 3 is a top plan view of the suspension spider.

Fig. 4 is a front elevation of Fig. 3.

Fig. 5 is a bottom plan view of the cone showing the cupping vanes forlift from very shallow water supplies.

The invention consists essentially of an inverted cone with the apexremoved, and with the cone being rotatably supported and driven to causethe water to be lifted through centrifugal action and discharged fromthe base or upper end of the cone.

The pump barrel or sleeve It is frusto-conical in form and is invertedwith the base II constituting the discharge end, and the apex I2 theintake, the discharge end being curled out and down as indicated at I3to an inverted U-shape in cross-section.

Mounted in the discharge end is a suspension spider I4 and which isimmovably secured in the upper end of the sleeve, and this spider has ahuh I 5 in which the suspension and drive shaft I 6 is fixed asindicated at II, this shaft being driven by any suitable source ofpower, depending on the conditions under which it is to be operated andthe available source of power. A series of equi-angularly spaced flutesI 8 extend from the discharge end to the bottom interiorly of the sleevewith the lower ends offset angularly relative to the upper ends toprovide a spiral which recedes from bottom to top relative to thedirection of rotation of the sleeve, and which functions to decreaseresistance and increase the upward flow of water by decreasingperipheral slippage with consequent frictional resistance of the water.Cupping vanes I9 are provided at the bottom of the barrel for operationin shallow ditches, creeks and the like, for providing initial lift ofthe water into the end of the sleeve. These vanes can be eliminated ifthe water is of sufiicient depth to allow suitable submersion of theintake end of the barrel.

The combined discharge chamber and supporting frame consists of ahousing having a passage in the bottom wall 28 for the sleeve, with anupturned wall 2i clearing the outside wall of the sleeve and inside wallof the curl and extending upwardly therein almost to the return bend,and also has a passage 22 provided in the top wall 23 to pass the barrelincluding the curl, so that the barrel can be inserted through the top,and this housing has a discharge 24 and is also provided with a flangeor cars 25 for securing to a u" rigid base 26, the housing being ofvolute form as indicated.

A cover member 21 forms a closure for the top of the housing and isremovably secured as indicated at 28, and this cover ha an axial bearing29 for the drive shaft and a thrust hearing 30 for support of the pumpthrough the shoulder provided on the drive shaft, motor mounting pads 3|being provided on this cover.

For assembly, the housing is mounted on a rigid base, the drive shaft ispassed through the thrust bearing and thence through the axial bearingin the cover, then into the hub on the suspension spider and fixedtherein. The spider is next secured in the top of the barrel asindicated at 32 access being had through the discharge passages 33 inthe side walls of this spider.

As will be noted, when the pump is rotated, the water climbs the wallsthrough centrifugal action with the flutes preventing peripheral lagwith consequent induced friction and transferring this lag to actuallift, providing highest efiiciency in water lift in relation to thepower consumed. Obviously, the greater the degree of divergence frombottom to top, and the greater the speed, the greater the volume ofwater that will be delivered.

I claim:

A pump comprising a frusto-conical sleeve invertedly mounted and havinga curl formed outwardly and downwardly to inverted U-shape at its upperend, a discharge housing for receiving water discharged from said sleeveand having an inner upturned flange from the bottom there- 4 of to fitabout the upper end of the sleeve within said curl, said dischargehousing surrounding the upper end of said sleeve and having a spirallyformed exterior wall terminating in a discharge opening and having aninturned flange at the top with the opening within the flange having adiameter greater than the maximum diameter of said sleeve for passage ofthe sleeve therethrough for assembly, a cover removably secured oversaid opening to said inturned flange and having an axial bearing, aspider having side walls having a plurality of extensive openings formedtherethrough for discharge of water from said sleeve, and having a topwall having an axial hub having a bore, with the lower end of the sidewalls frictionally fitting within the upper end of said sleeve and beingaffixed thereto, a shaft rotatable in said bearing and having a thrustmember for axial support on the top of said bearing and having its lowerend fixed in said bore for support and for rotational driving of saidsleeve.
